“Congratulations to The Queen and The Duke of Edinburgh as they celebrate their Platinum Wedding anniversary,” she said.

“They have devoted their lives to the service of the UK and the Commonwealth – my best wishes to them both on this special occasion.” Mrs. May added.

According to BBC news, Queen Elizabeth who is the longest serving on the throne, becomes the first British monarch to celebrate a platinum wedding anniversary.

To commemorate this, the church’s bell will ring for more than three hours.

“While the couple’s marriage has remained strong, three of their four children have seen their unions end in divorce, most notably heir Prince Charles’s ill-fated union with his late first wife Princess Diana.” Reuters reports
